OK, here's the first few pages of The Klingon Gambit:
Captain’s Log: Stardate 4720.1
Mapping of the Class-Q type planet, Delta Canaris IV, continues. This planet, discovered three years into our five year mission, is providing a needed break from deep space routine for the crew. The violent gravity waves emanating from the planet require constant orbital corrections, but the added work might prove worthwhile due to the possibility of life on the planet. Sensor readings are positive although in a part of the life-spectrum indicating beings unlike any previously discovered by a Federation starship. Excitement among the crew runs high. Morale has never been better.
Captain James T. Kirk felt the deck of the Enterprise vanish from under his feet. Grabbing a handrail, he steadied himself until the gravity fluctuations had passed. He glanced around the bridge and saw his officers busy themselves counteracting the adverse influence of still another gravity wave from the planet below.
“Mr. Sulu, report,” he ordered.
“Orbital corrections already made, sir,” said the efficient helmsman. Sulu continued to punch in orders to the ship’s control computer, his fingers almost a blur. Kirk nodded. The Asian knew his job and did it well. The captain continued his visual inspection of the bridge.
“Lt. Uhura, are those gravity waves affecting communications?”
“No, sir,” she answered. “Subspace is clear all the way to Starbase Sixteen. Do you wish to transmit now?”
“Not immediately. I still have to finish the annual efficiency report.”
“And if subspace transmission wasn’t possible, you wouldn’t have to do the report right away?” The Bantu woman’s eyes sparkled.
“I didn’t realize my motives were so transparent to the crew,” said Kirk tiredly. “Those reports are due too often. I’d rather be with Mr. Spock, seeing what that planet down there really has to offer.” He looked at the viewscreen and the dancing, shifting rainbow of the planet’s methane atmosphere. “It looks just like Jupiter, even to the large red spot,” he said, more to himself than to his communications officer.
“The similarity ends there, Captain,” came the level voice of Mr. Spock. The Vulcan had come onto the bridge, and Kirk hadn’t even noticed, being too engrossed in the sight of the gas giant. “Computer analysis of our previous sensor readings indicates life-forms similar to a sheet of paper.”
“How’s that, Mr. Spock?” Kirk looked at the imperturbable science officer, wondering if the Vulcan wasn’t deliberately baiting him. He had noticed a sly sense of humor creeping into the Vulcan’s words from time to time, but he had always discounted that as his own facile imagination at work. Humor wasn’t logical and, above all else, Spock valued logic.
“This is a new life-form, probably sentient.”
“Probably?”
“A ninety-four point two percent probability, Captain. The life-forms are slightly larger than your hand and less than a millimeter thick, due to the intense gravity of the planet. We have detected distinct roadways, structures believed to be cities and even indications of an ammonia ocean spanning trade.”
“But they’re only a millimeter thick?”
“Less than a millimeter. The exact thickness fluctuates due to food intake, movement and—”
“Thank you, Mr. Spock.” Kirk sighed. “I would like to know more, but I am afraid I must leave it in your capable hands for the moment. The annual efficiency and promotion reports are due at Starbase all too soon. I’d be more than happy to have you file the reports except it is a captain’s duty, and you are more efficiently employed studying Delta Canaris IV.”
“Logical,” agreed Spock, turning to his computer. His fingers inputted information as he stared into the blue dimness of his console display. Kirk knew the Vulcan was lost in a world of rapidly changing data, correlating it, digesting it and producing logical hypotheses for inclusion in the final report on the planet.
Reports, snorted Kirk to himself as he turned away. His life was plagued by a continual flood of reports. Status reports to Starfleet Command, matériel reports, utilization reports, efficiency reports—a starship captain had to be more of an accountant than a commander these days.
“Mr. Spock, you have the conn,” he said, going to the turbo-elevator. The movement of the elevator didn’t affect him like the fluctuations caused by the gravity waves from the planet. Long years in space had inured him to this familiar motion. The pneumatic hissing ceased, and the doors opened onto the deck containing his quarters. He had barely gotten to his desk when he remembered a disciplinary problem that he had failed to attend to earlier. Kirk punched the call button on the desk and said, “Mr. Scott to captain’s quarters immediately. And bring your chief engineer with you.”
He had just begun work on the reports when his door chime sounded.
“Come.” Kirk straightened as he saw Scott and the engineering chief stiffly enter the room and stand at ramrod attention in front of him.
“Reporting as ordered, sir,” said the dour Scots officer. “And I brought Chief McConel with me.”
Kirk found it hard to look with displeasure on the chief. Very attractive, she kept her red hair pulled back from her forehead and held in a small knot at the side. He saw a perfect complexion marred only by a trace of grime on one cheek, piercing green eyes . . . and a mind that was as agile as her lithe body.
“Chief McConel, are you aware that gambling is not allowed aboard ship?”
“Aye, sir,” she said, her slight burr a companion to Scott’s.
“You’re not denying that you were caught with elaborate gambling equipment in the engine room, are you?”
“No, sir, I am not.”
Kirk sighed. “Chief—Heather—I don’t care if there are games running. They keep the crew busy during slack times. You know that. This whole matter would never have reached my attention officially if you hadn’t rigged the roulette wheel with that laser.” Kirk leaned back, trying hard not to smile. “Tell me, how did you do it?”
“’Twas but a wee bit of hocus-pocus, sir,” she said, brightening. “The roulette ball is painted black. A mite of a laser beam against the ball and it dances to whatever tune I choose.”
“So that’s how . . . ” Kirk bit off his words. He had often wondered how he could have lost so much of his pay in such a short time at a casino on Argelius II. The captain shook himself back to the issue at hand. “Chief McConel, you will dismantle your gaming equipment—and that still you so cleverly hid in the machine shop—and put yourself on back-to-back shifts until I relieve you of the extra duty. Perhaps the added work will burn up that surplus energy of yours now being diverted to rigged games of chance.”
“Aye, aye, sir.”
“Dismissed. And Mr. Scott, a word with you in private.” They both watched the chief leave, her behind twitching just the right amount as she went through the door. Scotty’s heavy exhalation told Kirk more than words could have.
“She’s quite pretty, isn’t she, Scotty?”
“Aye, Captain, thot she is.”
“And you let her get away with rigging the roulette wheel. It’s you I should have on punishment duty, but I’m letting you both off this time. Nothing will be entered on her record. I don’t want this showing up on the Enterprise’s efficiency report. Those desk-skippers at Starfleet would jump all over something like this. I know you won’t stop the gambling—you shouldn’t—but don’t let me hear any more about cheating. We will have fair contraregulation gambling aboard this ship while I am captain. Do I make myself clear?”
“Pairfectly, sair!” The burr heightened in his words, and Kirk knew that Scotty wouldn’t let his feelings for the chief get in the way of his duty again.
“Good. Now let’s forget about those reports for a minute and have a little—”
The buzz of the ship’s intercom interrupted him. He stabbed down on the call button and said, “Kirk here.”
“Captain, a message from Starfleet Command.” Uhura sounded excited.
“Flash it on the screen, Lieutenant.”
“I can’t, sir,” she said. “It’s encoded and tagged. ‘For Captain’s Eyes Only.’ You have to decode it yourself, sir.”
Kirk felt momentary surprise at this. Highest priority messages were routinely squirted along in microbursts and received through devious computer-controlled equipment, making interception highly unlikely. To further encode a message was almost unheard of.
Almost.
“Send the coded message down by courier, Lieutenant,” he ordered. Looking up at his engineering officer, he said, “Dismissed, Scotty. We’ll have to have that drink later.”
“Aye, sair. Be looking forward to it!” Smiling, the engineer left.
Kirk’s attention focused on his tiny viewing screen, as soon as the security man delivered the message cassette. Row after row of numbers paraded out until the viewing area was filled. Leaning over, he opened the captain’s safe, keyed only to his palm-print. The small decoding device inside hummed as he began copying the numbers displayed on the screen. When the message became intelligible, his face stiffened. Erasing the words, he activated the ship intercom.
“Bridge. Mr. Spock.”
“Yes, Captain?” came the calm tones of his first officer.
“Lay in a course for Alnath II immediately. Warp factor eight.”
“That is emergency speed, Captain.”
“Aren’t the engines up to it?” snapped Kirk.
“Of course they are, sir.”
“Warp factor eight, Mr. Spock. Our presence is required at the start of another interstellar war.” He sagged back in his seat for a moment, then hastened to get to his bridge. The Enterprise had to be made battle-ready before arrival.
Every character but Kirk is identified by her or his species, race or ethnicity. That's pretty racist.
Kirk's reaction to Heather McConel speaks for itself. So, it's pretty sexist.
And the writing is, to my eyes, nothing short of dreadful.
I used to make a point of buying non-Trek SF books by Trek writers. But I made an exception for Vardeman, and never did get around to adding any of his books to my library.
….it's impossible to reconcile all the inconsistencies.
